The application of genetic algorithms for shape control with piezoelectric patches—an experimental comparison

TL;DR: In this article, a finite element model based on Mindlin plate theory was used to characterize the behaviour of the structure and the actuators. But the authors focused on the development of an efficient and general methodology, based on genetic algorithms, for the determination of the optimal actuation voltages needed to apply to the piezoelectric actuators in such a way that a pre-defined shape of a structure is achieved.
Journal ArticleDOI

Clear-PEM: A dedicated pet camera for improved breast cancer detection

TL;DR: The concept of Clear-PEM, the system presently developed in the frame of the Crystal Clear Collaboration at CERN, will be a dedicated scanner, offering better perspectives in terms of position resolution and detection sensitivity.
Journal ArticleDOI

Fast RICH detector with a cesium iodide photocathode at atmospheric pressure

TL;DR: In this paper, a Cherenkov angular resolution of 8 mrad is obtained by detecting a mean of 8 photoelectrons per ring per ring, and the results obtained with photons impinging at a large angle on the CsI layer are presented and discussed in comparison with higher quantum efficiencies observed under different experimental conditions.
